Explanation:
The area of any given sheet of paper is 8.5*11 = 93.5 square inches.
Divide the volume over this area to get the height of the stack
187/(93.5) = 2
The stack is 2 inches tall.
Extra info: The thickness of each piece of paper is 2/500 = 0.004 of an inch which approximates to about 0.1016 mm.
|x-3|<2

Ayudaaaaaaa pleaseeeee
Recuerda que
• |x| = x si x ≥ 0
• |x| = -x si x < 0
Necesitas considerar dos casos:
• si x - 3 ≥ 0,
|x - 3| < 1 ⇒ x - 3 < 1 ⇒ x < 4
• si x - 3 < 0,
|x - 3| < 1 ⇒ -(x - 3) = 3 - x < 1 ⇒ -x < -2 ⇒ x > 2
Entonces la solución consta de todos los números reales x tales que x > 2 y x < 4, o simplemente 2 < x < 4.
El método para resolver las otras desigualdades es el mismo.
|4x + 1| > 0 ⇒ 4x + 1 > 0 o -(4x + 1) > 0
… ⇒ 4x + 1 > 0 o -4x - 1 > 0
… ⇒ 4x > -1 o -4x > 1
… ⇒ x > -1/4 o x < -1/4
⇒ x ≠ -1/4
|x - 1| < 5 ⇒ x - 1 < 5 o -(x - 1) < 5
… ⇒ x - 1 < 5 o -x + 1 < 5
… ⇒ x < 6 o -x < 4
… ⇒ x < 6 o x > -4
⇒ -4 < x < 6

I can't understand with your question but I think the qustion is like ☝
The value of the expression 8 x 4² + 10 - 5 x 108 x 42 + 10 - 5 x 10 is -22,582
To calculate the value of the given expression 8 x 4² + 10 - 5 x 108 x 42 + 10 - 5 x 10.
we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.
Let's break down the steps:
Calculate the exponent: 4² = 4 x 4 = 16.
Multiply 8 by 16: 8 x 16 = 128.
Multiply 5 by 108: 5 x 108 = 540.
Multiply 540 by 42: 540 x 42 = 22,680.
Multiply 5 by 10: 5 x 10 = 50.
Now, the expression becomes: 128 + 10 - 22,680 + 10 - 50.
=-22,582
Therefore, the value of the expression 8 x 4² + 10 - 5 x 108 x 42 + 10 - 5 x 10 is -22,582

For what value(s) of k will the relation not be a function? S={(2-|k+1|,4), (-6,7)}
A relation is the relationship between variables. When each input has one output, the relation is a function. When the value of k is 5 or 3, the relation will not be a function.
Given that:
[tex]S= \{(2-|k+1|,4), (-6,7)\}[/tex]
For S, not to be a function, 1 domain element must point to more than one range elements.
This means that:
[tex]2-|k+1| = 6[/tex]
Collect like terms
[tex]-|k+1| = 6 - 2[/tex]
[tex]-|k+1| = 4[/tex]
Multiply by -1
[tex]|k+1| = -4[/tex]
Remove absolute bracket
[tex]k+1 = -4\ or\ k+1 = 4[/tex]
Solve for k
[tex]k =-1 -4\ or\ k= -1+4[/tex]
[tex]k =-5\ or\ k= 3[/tex]
Hence, when k is 5 or 3, the relation will not be a function.

2) Jessica went to the mall. She paid $14.57 on shorts and $10.20 on pants
with two $20 bills. She went to 2 shops. How much money did Jessica get in change?
Answer:
15.23
Step-by-step explanation:
First, you add 14.57 with 10.20 which equals 24.77.
then you minus 24.77 from 40 which equals 15.23!
hope this helps you :D
Hello :D
To do this you need to do:
$20 x 2 = $40.00
$14.57 + $10.20 = $24.77
$40.00 - $24.77 = $15.23
The answer is $15.23. I hope this helps :)
